BACKGROUND 1. Technical Field

This disclosure relates to a camera housing, and more specifically, to acamera housing with an integrated expansion module for adding expandedfeatures to an existing camera.

2. Description of the Related Arts

The problem of conveniently carrying, accessing, and using a cameraunder various operating conditions has existed since the beginning ofhand-held photography. It has become even more of a problem in recentyears as a growing number of photographers attempt to take actionphotographs or videos while participating in fast-paced physicalactivities such as surfing, snorkeling, skiing, mountain biking,kayaking, rafting and so on.

In order to accommodate photography during such physical activities,camera manufacturers have produced cameras that are simple to operate,low cost, lightweight, and have compact form factors. These cameras canbe secured using various mounts, harnesses, or straps to allow a user tokeep one or more hands free for the physical activity. For example,camera wrist strap systems are available that provide a compact andlightweight camera together with a strap for securing the camera to auser's wrist. This configuration allows the user to easily access,operate, and then quickly secure the camera. Furthermore, the camera issmall and light enough that it does not handicap the user while engagingin physical activity. Alternatively, helmet style camera systems allow auser to mount a compact and lightweight camera to a helmet. Other typesof camera systems may include mounts for securing a camera to a bumperor windshield of a car to capture images or video while driving.

While such camera systems have become increasingly popular amongphotographers, these camera systems often lack features available inmore traditional cameras. For example, wrist-mounted or helmet mountedcamera systems often lack display screens in order to keep the camerasystems small, lightweight, and low cost. While features such as adisplay screen may be desirable in some scenarios, it may not be usefulin other scenarios. For example, a display screen would not be usefulwhen the camera is mounted to a helmet, but may be useful when thecamera is strapped to a wrist. Thus, a user may be reluctant to purchasea camera that includes the feature, particularly if the feature adds tothe cost, physical size, and weight of the camera. Furthermore, ascamera manufacturers produce cameras with new and/or improved features,users may become frustrated by the need to periodically purchase newcameras in order to have the new features available to them. There islacking, inter alia, a camera system that provides expanded electronicfunctionality to an existing camera.

Camera System Configuration

A camera system includes a camera housing with an embedded expansionmodule for providing one or more expanded features to an existingcamera. It is noted that the camera can be configured as a still picturecamera or a moving picture camera (e.g., video). FIGS. 1a-c illustratevarious views of the camera system in accordance with one embodiment.The camera system includes, among other components, a first housingportion 102 and a second housing portion 140 (i.e. door 140),collectively referenced herein as housing 100. In one embodiment, thefirst housing portion 102 includes a front face with four sides (i.e. atop side, bottom side, left side, and right side) structured to form acavity that receives a camera 110 (e.g. a still camera or video camera).A second housing portion 140 (or door 140) detachably couples with thefirst housing portion 102 opposite the front face of the first housingportion. The first housing portion 102 and second housing portion 140are collectively structured to enclose the camera 110 within the cavitywhen the second housing portion 140 is secured to the first housingportion 102 in a closed position.

The camera housing 100 encloses and protects the camera 110. The camerahousing 100 is particularly advantageous when using the camera 110during periods of physical activity when the camera 110 may besusceptible to damage. For example, without the housing 100, the camera110 may become scratched or otherwise damaged when used during physicalactivity. The camera 110 is removable from the housing 100 so that ifthe housing 100 becomes scratched or damaged, it can be easily replacedat a much lower cost than replacing the camera 110 itself.

In one embodiment, the camera 110 (and camera housing 100) has a smallform factor (e.g., a height of approximately 4 to 6 centimeters, a widthof approximately 5 to 7 centimeters, and a depth of approximately 2 to 4centimeters), and is lightweight (e.g., approximately 50 to 150 grams).The camera housing 100 can be rigid (or substantially rigid) (e.g.,plastic, metal, fiberglass, etc.) or pliable (or substantially pliable)(e.g., leather, vinyl, neoprene, etc.). In one embodiment, the camerahousing 100 may be appropriately configured for use in various elements.For example, the camera housing 100 may comprise a waterproof enclosurethat protects the camera 110 from water when used, for example, whilesurfing or scuba diving.

Portions of the camera housing 100 may include exposed areas to allow auser to manipulate buttons on the camera 110 that are associated withthe camera functionality. Alternatively, such areas may be covered witha pliable material to allow the user to manipulate the buttons throughthe camera housing 100. For example, in one embodiment the top face ofthe camera housing 100 includes an outer shutter button 112 structuredso that a shutter button of the camera 110 is substantially aligned withthe outer shutter button when the camera 110 is secured within thecamera housing 100. The shutter button of the camera 110 isoperationally coupled to the outer shutter button 112 so that pressingthe outer shutter button 112 allows the user to operate the camerashutter button. In one embodiment, the front face of the camera housing100 includes a lens window 104 structured so that a lens of the camera110 is substantially aligned with the lens windows 104 when the camera110 is secured within the camera housing 100. The lens window 104 can beadapted for use with either conventional lens of the camera 110, a wideangle lens, or any other specialized camera lens. In one embodiment, thelens window 104 and/or lens of the camera 110 is removably attachable tothe first portion of the camera housing 102 and comprises a thirdportion of the housing 100. In this embodiment, the lens window 104comprises a waterproof seal so as to maintain the waterproof aspect ofthe housing 100. Alternatively, the lens window 104 is permanently fixedto the housing portion 102.

In one embodiment, the camera housing 100 includes one or more securingstructures 120 for securing the camera housing 100 to one of a varietyof mounting devices. For example, in one embodiment the camera housing100 can be secured to a wrist strap that secures the camera to a user'swrist. An example of such a camera system is described in U.S. Pat. No.6,955,484 entitled “Harness System for Attaching Camera to User” toNicholas Woodman, the content of which is incorporated by referenceherein in its entirety. In another embodiment, the housing 100 couplesto a helmet mount via the securing structure 120 for mounting the camerato a helmet. In yet another embodiment, a car mount for mounting thecamera to a car couples to the securing structure 120. In yet otherembodiments, other type of mount, strap, or securing devices known tothose of ordinary skill in the art couple to the securing structure 120for securing the camera to various other apparatuses or body parts.

In one embodiment, the second housing portion 140 comprises a door 140(shown in the open position in FIGS. 1a-c ) that allows the camera 110to be removed from the housing 100. The door 140 of the housing 100pivots around a hinge 142 that allows the door 140 to be opened or shut.In one embodiment, a first fastening structure 144 located on the topface of the camera housing 100 detachably couples to a second fasteningstructure 146 on the door 140 of the housing 100. The fasteningstructures 144, 146 secure the door 140 to the first portion 102 of thecamera housing 100 in a closed position when coupled. FIGS. 2a-billustrate embodiments of the camera housing 100 with the door 140secured in the shut position using the fastening structures 144, 146.For example, in one embodiment, the fastening structure 144 comprises ahook-shaped lateral bar and the fastening structure 146 comprises anL-shaped bar. The fastening structure 144 can pivot upwards to allow thedoor 140 to close and can then be pressed down around the fasteningstructure 146 to hold the door 140 in the closed position. In differentembodiments, fastening structures for securing the door 140 can include,for example, a button assembly, a buckle assembly, a clip assembly, ahook and loop assembly, a magnet assembly, a ball and catch assembly,and an adhesive assembly, or any other type of securing mechanism.

In one embodiment, the housing 100 includes a watertight seal so thatthe housing 100 is waterproof when the door 140 is shut. For example, inone embodiment, the door 140 includes a sealing structure positioned onedges of the door 140. The sealing structure provides a watertight sealbetween the first portion of the camera housing 102 and the door 140when the first securing structure 144 on the top face of the camerahousing 100 is coupled to the second securing structure 146 on the topedge of the door 140.

In one embodiment, the door 140 detachably couples from the firsthousing portion 102 at the hinge 142. FIG. 3 illustrates an exampleembodiment of the camera housing 100 with the door 140 uncoupled fromthe first housing portion 102. In one embodiment, an outer hingestructure 152 on the bottom edge of the door 140 detachably couples toan inner hinge structure 154 on the bottom edge of the first housingportion 102 to form the hinge 142. For example, in one embodiment, theouter hinge structure 152 comprises one or more hook-shaped protrusionsstructured to securely fasten to a rod-shaped member of the inner hingestructure 154. Other mechanisms for coupling the door 140 to the housing100 may also be used in various alternative embodiments.

The door 140 of the camera housing 100 has an integrated expansionmodule 130 including a communications interface 132 for communicativelycoupling to the camera 110. The integrated expansion module 130comprises electronics that add one or more functions to the camera 110.The interface 132 facilitates data communication between the integratedexpansion module 130 and a coupling interface 116 of the camera 110 inorder to provide expanded functionality to the camera 110.

In one embodiment, the interface 132 on the housing 100 communicativelycouples to a camera interface 116 commonly available on existing camera110. For example, most digital cameras include an interface fortransferring images and/or video captured by the camera to a PC or otherstorage device. Such an interface also often allows a user to supplyfirmware updates to the camera 110. By applying appropriate firmwareupdates to the camera 110 and/or by receiving and manipulating imagedata retrieved from the camera 110, the integrated expansion module 130can provide the expanded features to the camera 110. In addition, theinterface can be used for various data transfers between the camera andthe expansion module 130 to facilitate a variety of camera functions aswill be described below. In one embodiment, the interfaces 132, 116comprises a Universal Serial Bus (USB) interface (e.g., USB A, USB B,mini USB (A or B) or micro USB (A, B or AB)). Alternatively, a differenttype of interface may be used such as, for example, a serial interface,a parallel interface, a FIREWIRE interface, an ETHERNET interface, andso on. In other embodiments, a wireless interface (e.g., BLUETOOTH) maybe used.

In one embodiment, the integrated expansion module 130 is removable fromthe door 140 so that different expansion modules 130 providing differentfeatures to the camera can be swapped in and out. Alternatively, theentire door 140 is detachable from the first housing portion 102 (asillustrated in the embodiment of FIG. 3) and can be swapped with otherdoors 140 having different expansion modules 130 providing differentfeatures. Examples of different expansion modules for use with thecamera system 100 are described in further detail below.

FIG. 4 illustrated a variety of different types of integrated expansionmodule 130 providing different functions to the camera 110 depending onthe user's needs. According to various embodiments, the integratedexpansion module 130 can comprise one or more of a display module 410, ashot positioning module 420, a wireless module 430, a storage module440, an expansion power supply 450, an audio capture module 460, a dataacquisition module 470, an image processing module 480, a night visionmodule 490, and an expansion input/output (I/O) module 495. An expansionmodule 130 may also comprise a module that includes a combination offunctions (e.g., a storage module 440 and an audio capture module 460enclosed within a single housing portion 140). In a typical use, a usermay have several different types of expansion modules 410-495(collectively referred to as expansion module 130 for ease ofdiscussion) available. The user can then swap in and out the differentexpansion modules 130 depending on the desired functions. Embodiments ofthe camera system 100 using the different types of expansion modules 130(e.g., 410-495) are described in more detail below.

In another embodiment, the integrated expansion module 130 of the camerahousing 100 comprises a “shot” (e.g., photo or video shot) positioningmodule 420 configured to assist the user in aligning the camera when theviewfinder or external display is outside the user's view (e.g., whenthe housing 100 is mounted to a helmet). One example embodiment of asystem using the shot positioning module 420 is illustrated in FIG. 6.In this embodiment, the shot positioning module 420 includes acommunication interface that transmits image information from the camera110 to a remote preview screen 604 that can be attached to a user's armor wrist. In one embodiment, the shot positioning module 420 includes awireless interface (e.g., Bluetooth, Radio Frequency (RF), infrared(IR), 801.11a/b/g/n or other wireless protocol) that communicates withthe remote preview screen 504.

The wireless interface transmits the image currently in view of thecamera lens to the remote preview screen 604 for display. In oneembodiment, the shot positioning module 420 communicates with the remotepreview screen 604 via a two-way interface. In this embodiment, theremote preview screen 604 may have control buttons 606 that allow theuser to control various camera operations from the remote preview screen604. Alternatively, the communication interface may be a one-waycommunication such that the remote preview screen 604 only receives anddisplays image information from the camera 110 but does not send anyinformation or controls to the camera 110. In this embodiment, the userstill controls the camera 110 via the built-in camera buttons (e.g., theshutter button 114).

Camera Housing with Wireless Module

In another embodiment, the integrated expansion module 130 comprises anintegrated wireless module 430 that adds wireless connectivity to acamera 110 lacking wireless features.

Images or video captured by the camera 110 are transmitted to theintegrated storage module 440 via the communication interface 132.

Camera Housing with Expansion Power Supply

In another embodiment, the expansion module 130 comprises an expansionpower supply 450 for providing power to the camera 110. For example, theexpansion power supply may include an expansion battery that supplementsan internal battery of the camera 110 and provides additional batterylife to the camera 110. In another embodiment, the expansion powersupply 450 can include a solar charger that captures solar energy torecharge a battery. The expansion power supply may also be configured sothat rechargeable batteries providing power to the camera can berecharged through an expansion power supply 450 that comprises aninductive charging element or a capacitive charging element. In the caseof inductive charging, the communication interface 132 may couple withan inductive coil plate that inductively couples with the inductivecharger (which has its own coil). In the case of conductive charging,the communications interface 132 is configured to receive a dischargefrom a capacitive power source that is the expansion power supply 450.Alternatively, the expansion power supply 450 couples directly tobattery terminals of the camera 110 rather than coupling via theinterface 132.

Camera Housing with Audio Capture Module

In yet another embodiment, the integrated expansion module 130 caninclude an audio capture module 460 (e.g., a microphone or an interfacefor an external microphone) to capture and/or store audio data. In thisembodiment, the audio capture module 460 captures audio concurrentlywith the camera 110 capturing video. Alternatively, the audio capturemodule 460 can capture audio alone without any corresponding video.

Camera Housing with Data Acquisition Module

In yet another embodiment, the integrated expansion module 130 includesa data acquisition module 470 that acquires various data to store inassociation with images or video captured by the camera. For example, inone embodiment, the data acquisition module 130 capture GlobalPositioning System (GPS) data that provide positioning information. Suchpositioning information may be stored together with images and/or videoso that the user can record where the images and/or video were taken.For example, in one embodiment, the GPS module automatically inserts aposition stamp on a captured image or video indicating the location thatthe image or video was captured. Similarly, the data acquisition module470 can include, for example, an accelerometer, altimeter, clock,thermometer, humidity sensor, barometer, heart rate meter, light sensor,and so on. Any of the captured information can be stored withphotographs or video or automatically inserted into the images or videoto provide the user with information relating to the captured scene.

Camera Housing with Image Processing Module

In yet another embodiment, the integrated expansion module 130 includesan image processing module 480. The image processing module 480 receivesimages and/or video from the camera and performs various imageprocessing functions such as, for example, modifying brightness,contrast, saturation, hue, resolution, aspect ratio, and so on. In oneembodiment, the image processing module converts images or videoscaptured in a 4:3 aspect ratio to an image or video 16:9 aspect ratio orvice versa. In one embodiment, the image processing module 480 includesa digital signal processor (DSP) chipset that is configured to “stretch”pixels gradually starting at a center of a captured image (stretch=0)working outward towards each edge and/or corner of the image(stretch=maximum_set). The number of directions for the stretch can beany integer. However, in one embodiment the number of directions ofstretch are a factor of 2 for a 4 sided picture radiating in oppositedirections from the center of an image. For example, the processingmodule 480 can stretch an image in 2 directions (any two oppositeedges), 4 directions (each edge), 8 directions (each edge and eachcorner) and the like.

In an alternate embodiment, a wide angle lens couples with the camera110 and captures images in 16:9 format and the image processing module480 coverts it into a 4:3 format. In one embodiment the DSP isconfigured so that the captured 16:9 image is cropped into a 4:3 size.Alternately, the DSP is configured so that the pixels are “squeezed”with the maximum squeeze at the edges and corners (squeeze=maximum_set)and the minimum or no squeeze closer to the center of the image(squeeze=0).

Camera Housing with Night Vision Module

In yet another embodiment, the integrated expansion module 130 caninclude a night vision module 490 to add night vision capabilities to anexisting camera 110. The night vision module 490 may utilize anyconventional night vision technology such as, for example, infrarednight vision, thermal night vision, and so on. In one embodiment, thenight vision module 490 operates with a specialized lens designed fornight vision image and/or video capture.

Camera Housing with Expansion I/O Module

In yet another embodiment, the integrated expansion module 130 caninclude an expansion input/output (I/O) module 495 that allows otherexternal devices to communicate with the camera 110 through a variety ofpossible interfaces. For example, the expansion I/O module 495 may adaptthe standard communication interface of the camera 110 to be able tocommunicate with external devices via interfaces such as, for example, aUSB interface, a serial interface, a parallel interface, a FIREWIREinterface, an ETHERNET interface, a wireless interface, and so on. Theexternal device can then perform functions such as controlling operationof the camera 110 or acquiring and/or processing data from the camera110.

Additional Embodiments

In other additional embodiments, the door 140 of the camera housing 100can have various shapes and sizes to accommodate cameras 110 ofdifferent thicknesses and shapes. Thus, a user may have a set ofremovable doors 140 that can be swapped in and out depending on the sizeand shape of the camera 110 being used. In some embodiments, the camera110 may also accommodate various expansion modules that attach directlyto the body of the camera, an example of which is described below withreference to FIGS. 8a-b and 9a-b . Thus, various additional embodimentsof the housing door 140 can also be sized and shaped to accommodateexpandable cameras having expansion modules of different sizes andshapes. In one embodiment, a door 140 may have various cut-outs, vents,or other pass-throughs to provide improved cooling to the camera 110and/or better audio capture if the camera 110 is equipped with amicrophone. Thus, a user may swap between a vented camera door or asolid-bodied waterproof back door depending on the circumstances and thetype of camera 110 being used.

The described housing 100 may also be adapted for a wider range ofdevices of varying shapes, sizes and dimensions besides cameras. Forexample, the housing 100 with expansion module 130 may be used to addexpanded features to electronic devices such as cell phones, musicplayers, PDAs, GPS units, or other portable electronic devices.

Expansion Module for Camera Body
